The role of a capacitor in an electronic circuit is to store and release electrical energy. It acts as a passive component able to store electric charge temporarily. When a voltage is applied across the two terminals of a capacitor, it charges up and stores the energy in an electric field between two conductive plates separated by an insulating material known as a dielectric.
Capacitors have the ability to block direct current (DC) while allowing alternating current (AC) to pass through. They are commonly used in electronic circuits for various purposes, such as:
Overall, capacitors serve a vital role in electronic circuits by providing energy storage, signal conditioning, and frequency control, a**** various other applications.
In summary, the role of a capacitor in an electronic circuit is to store and release electrical energy, block DC while allowing AC to pass, smooth out voltage fluctuations, provide timing and oscillation control, couple or decouple signals, and condition electrical signals, a**** other applications.
